I work for a fixed wireless provider, and our mpls-capable backhauls are
all running mpls with 9200 MTU with no problem.  The only weirdness I
encounter is if I have multiple equal-cost routes to the same location, one
over MPLS and one not, end up having ping/unreachable issues from my
monitoring equipment.  The solution has been to cost one path (the MPLS)
lower than the other.  The only other problem I had was with radio's that
didn't support larger 9000+ byte MTU packets - we've phased that radio out
for now.  if you run MPLS with 1500 byte MTU, you'll have issues with 1500
byte packets with the DF-bit set.  That was a nasty discovery in the
production network, your mileage will not vary with that problem.
